C/C++应用--Window下获取硬件信息（CPU, 硬盘，网卡等）
一、头文件如下：
#include <Windows.h> #include <string> #include <iostream> #include <winnt.h> #include <tchar.h> #include <IPHlpApi.h> #pragma comment(lib,"ws2_32.lib") #pragma comment(lib,"Advapi32.lib") #pragma comment(lib, "Iphlpapi.lib") using namespace std; // ***** global macros ***** // #define GBYTES 1073741824 #define MBYTES 1048576 #define KBYTES 1024 #define DKBYTES 1024.0 class CSysInfo { public: CSysInfo(); ~CSysInfo(); public: const std::string GetOSVersion(); void SafeGetNativeSystemInfo(LPSYSTEM_INFO lpSystemInfo); const std::string GetCPUInfo(); const std::string GetMemoryStatus(); void GetNetCardAndIPInfo(std::string &adapter_info, std::string &MAC_address, std::string &IP); const std::string GetComputerUserName(); BOOL GetHardDiskInfo(LPTSTR pModelNo, LPTSTR pSerialNo); void ToLittleEndian(PUSHORT pWords, int nFirstIndex, int nLastIndex, LPTSTR pBuf); };
二、cpp如下：
